    Abstract: A first conductive region having a second conductivity type is formed in a first semiconductor over a first dielectric isolation region and having a first conductivity type. A second semiconductor having the first conductivity type is formed over the first conductive region and the first semiconductor. Isolation structures are formed extending through the second semiconductor and the first semiconductor to the first dielectric isolation region, thereby defining a first well of the second semiconductor contained within the isolation structures and a second well of the first conductive region contained within the isolation structures. A charge-storage node is formed over the first well. Source/drain regions having the second conductivity type are formed in the first well adjacent the charge-storage node. A control gate is formed over the charge-storage node. A first contact is formed to the first well. A second contact is formed to the second well through the first well.

    Abstract: Stacked imager devices that can determine distance and generate three dimensional representations of a subject and associated methods are provided. In one aspect, an imaging system can include a first imager array having a first light incident surface and a second imager array having a second light incident surface. The second imager array can be coupled to the first imager array at a surface that is opposite the first light incident surface, with the second light incident surface being oriented toward the first imager array and at least substantially uniformly spaced. The system can also include a system lens positioned to direct incident light along an optical pathway onto the first light incident surface. The first imager array is operable to detect a first portion of the light passing along the optical pathway and to pass through a second portion of the light, where the second imager array is operable to detect at least a part of the second portion of light.

  • Patent number: 9929229
    Abstract: Various embodiments includes a stacked open pattern inductor fabricated above a semiconductor substrate. The stacked open pattern inductor includes a plurality of parallel open conducting patterns embedded in a magnetic oxide or in an insulator and a magnetic material. A layer of magnetic material may be located above the inductor and below the inductor to confine electronic noise generated in the stacked open pattern inductor to the area occupied by the inductor. The stacked open pattern inductor may include a magnetic material directly contacts one of the conducting patterns and the substrate. The stacked open pattern inductor may be fabricated using conventional integrated circuit manufacturing processes, and the inductor may be used in connection with computer systems.
